Important Regulatory Information
Government Requirements
Certain governments require that instructions pertaining to connection to the telephone network be included in the
installation and operation manual. Specific instructions are listed in the following sections.
United States
Notice to Users of the Telephone Network
This equipment complies with Part 68 of the FCC rules. On the equipment is a label or silk screened text that
contains, among other information, the FCC registration number for this equipment. If requested, please provide this
information to your telephone company .
If your T1 equipment causes harm to the telephone network, the telephone company may discontinue your service
temporarily. If possible, they will notify you in advance. But if advance notice is not practical, you will be notified as
soon as possible. You will be advised of your right to file a complaint with the FCC.
Your telephone company may make changes in facilities, equipment, operations, or procedures that could affect the
proper operation of your equipment. If so, you will be given advance notice so as to give you an opportunity to
maintain uninterrupted service.
No repairs may be performed by the user. Should you experience dif ficulty with this equipment, refer to the
Sales and Service Information
Make the T1 network connection using a Universal Service Order Code (USOC) type RJ48C jack for single-line
installations and type RJ48H jack for multiline installations. Specify both the Service Order Code 6.0N, as well as the
proper Facility Interface Code, to the telephone company when ordering the T1 line. The T1 equipment can be
configured to support any of the framing format and line signaling techniques shown in the table below. The T1
equipment’s configuration must correspond to the T1 line’s parameters.

The Federal Communication’s Commission (FCC) requires that the end user (person responsible for operation and
maintenance of the equipment) file an affidavit with the local exchange carrier when connecting unprotected
Customer Premises Equipment (CPE) to the public T1 network. The T1 equipment is considered an unprotected CPE
because the analog through transmission gain paths, associated with the voice cards, are user adjustable. This
affidavit is required whenever digital terminal equipment without encoded analog content and billing protection is used
to transmit digital signals containing encoded analog content which is intended for eventual conversion into
voice-band analog signals and retransmitted on the network. This affidavit shall affirm that either no encoded analog
content or billing information is being transmitted or that the output of the device meets Part 68 encoded analog
content or billing protection specifications. An affidavit form has been provided for your convenience.

WARNING:
In order to maintain compliance with Part 68, FCC Rules and Industry Canada’s CS-03 Specification, the
transmit gain settings associated with the E&M, FXO and FXS V oice APMs must be set to ensure that:
— The absolute signal power of the encoded analog signals, other than live voice and network control
signaling, will not exceed –12 dBm when averaged over any 3-second interval.
— For network control signals (such as DTMF), the level will not exceed –3 dBm.
The E&M, FXO and FXS voice lines are to be connected to locally attached equipment only . Under no
circumstances should voice lines be used on exposed (outside) plant lines.
After the telephone company has installed the requested service and jack, you can connect the equipment to the

About the T1 Access Mux
Hot Swapping. Provides the ability to insert and remove APMs without
powering-down the housing, and without having to reconfigure the cards
each time they are moved.
The APM configurations travel with the NAM. When an APM is inserted or
removed, the NAM senses that an APM has been inserted or removed, and
can automatically make the appropriate changes to screens, configuration
options, and MIB objects.
— When an APM is inserted in a previously unassigned slot, the T1 access
unit configures the APM using the factory default configuration.
— When the same type of APM is inserted into a previously assigned slot,
the T1 access unit uses the configuration for the APM that previously
occupied the slot; the APM does not have to be reconfigured.
— When another type of APM is inserted into a previously assigned slot, an
alarm and trap are generated for the slot. If accepted, the factory default
configuration is loaded for the new APM type; if rejected, the new APM is
ignored and the previous configuration is retained.
The NAM can be removed without powering down the unit; however, all
system functionality is lost. When a NAM is removed and inserted into
another housing, it applies the NAM’s configurations from the previous
housing to the current housing.
— If the NAM is moved from a 2-slot housing to a 5-slot housing, the
operator can use the configuration of the APM in slot 02 of the previous
housing. APMs in slots 03 – 05 will be configured with the factory default
settings.
— If the NAM is moved from a 5-slot housing to a 2-slot housing, the factory
default configuration options are loaded.
— If the NAM is moved from a 2-slot or a 5-slot housing to a 14-slot
housing, the factory default configuration options are loaded.
Multiple User Interfaces. Provides multiple means for configuring,
operating, managing, and monitoring the unit.
Menu-Driven User Interface.
—
Provides an easy to use, menu-driven
interface for configuring and managing the T1 access unit locally or
remotely.
Access to the user interface can be through an async terminal (or other
VT100-compatible terminal), PC emulation, modem, or a Telnet session.

About the T1 Access Mux
Multiple Management Paths. Provides multiple methods for sending/
receiving management data.
—
Embedded Data Link (EDL)
. Provides a path for management data over
a performance channel between two nodes. The performance channel
uses 8 Kbps of bandwidth, and is embedded in the synchronous data
channel. If you choose this method, you must have a Sync Data port.
Direct Data Link (DDL)
—
. Provides a path between two nodes over the
T1/FT1 link itself, embedding the management data in the T1 bundle.
The management data always uses 1 DS0 (64 Kbps).
Facility Data Link (FDL)
—
. Provides the management path over the FDL of
the DS1 extended superframe (ESF). Using this method does not use
any customer data bandwidth, but requires end-to-end connectivity. If you
select this method, you may need to work with your service provider to
ensure that ESF framing is used and the required FDL management path
exists end-to-end.
COM Port
—
. Provides a physical path over the communications
port/interface for local user interface access or network IP connectivity
data management.
IP Connectivity. Supports connectivity within an IP network for up to 300 IP
host and/or network routes. Using the four management paths described
above, provides IP routing for SNMP, Telnet, and file transfer protocol (FTP)
messages connectivity without requiring direct connections.
DSX-1 Drop and Insert port(s) allows DTEs/PBXs that support the DS1
signal format to share the T1 network with other high-speed equipment. One
DSX-1 port is provided on the 9161 T1 NAM. The DSX APM (for use with the
9261 T1 NAM) provides two drop/insert ports.
Alarm and Fault Condition Indication. Provides the capability of attaching
a terminal or printer to display/print alarm messages.
Alarms or traps that are generated include: power supply, loss of signal, out
of frame, alarm indication signal, excessive error rate, primary and secondary
clock failure, yellow alarm signal received, misconfiguration, and APM failure.

Extensive Statistics Gathering. Provides a complete view of the network’s
and each data port’s performance through the statistical data collected from
those interfaces to assist in determining the duration of a condition or event.
— A total of 96 intervals (24 hours) of user and Telco statistical data is kept,
seven per screen page, over a 24 hour period, in 15-minute intervals.
— A total of 32 intervals (8 hours) of Synchronous Data Port statistical data
is kept, over an 8 hour period, in 15-minute intervals.
— Quick and easy access to any of the 96 sets of statistics is provided by
selecting a specific interval or occurrence timeframe. (Specifying an
occurrence timeframe is useful when you know about what time a
specific event occurred.)
— You can select a set of statistics to display at the following times:
following an event, preceding an event, immediately preceding and
following an event, or only those statistics that occurred at or after the
event that is the specified interval or time.
— Statistics collected measure or count the following: errored, unavailable,
severely errored, and bursty errored seconds, as well as controlled slip
seconds and loss-of-frame counts. In addition, yellow alarm, loss of
signal, excessive error rate, frame-synchronization bit error, and
line-code violation counts are kept for each 15-minute interval.
— The worst interval for each statistic is provided as an additional aid in
selecting statistical information surrounding trouble spots.
Configuration Upload/Download and Software Download Capability.
Provides quick, cost-effective software upgrades, and quick transfer of
configuration options to and from nodes using a standard file transfer protocol
(FTP).
Security. Provides multiple levels of security, which prevents unauthorized
access to the unit.
Security can be controlled by:
— Disabling any form of access to the unit.
— Requiring logins (login ID/password/access level combinations), with
three access levels to select from: read-only, limited-access, and
full-access.
— Enabling SNMP management, and specifying a community name and
access level Read or Read/Write.
— Enabling SNMP management, and specifying the IP addresses of only
selected NMSs.
Redundant power supply. Redundant load sharing supply (both AC and DC
versions available) for the 5-slot housing and the access carrier. Protects the
system from a service outage if one power supply fails.
Wall-Mount Bracket. Allows one 5-slot, or up to two 2-slot housings to be
mounted on a wall.

T1 Access Unit with High Speed Data
This application supports two ports of high speed data. The following diagram
depicts a router and a mainframe.
The data moving through the FEP and the cluster controller is heritage data that
is not available on the LAN. Because the T1 access unit includes two data ports,
the router-based data can easily be added to the network without disrupting the
existing network operations.
The data rates available to the two applications can be easily changed. This
allows the router connection to increase in speed. It also allows the FEP-based
data to reduce its data rate as the amount of data transmitted on this route
declines naturally over time.

T1 Access Unit with High Speed Data and E&M
Analog PBXs (shown in the following diagram) typically communicate on trunk
lines (lines between switches) with a type of communications protocol called
E&M.
The T1 access unit fully supports this application. The T1 access unit supports up
to three 8-port E&M APMs. In the example shown in the diagram, eight time slots
could be assigned to the voice ports, two time slots to the FEP-Cluster controller
link, and up to 14 time slots to the router link. This provides the following:
Voice – Eight telephone calls
FEP-CC – 128 kbps
Router – 896 kbps

T1 Access Unit with High Speed Data and APL
In the example shown in the following diagram, E&M analog voice APMs are
used to transport analog private line (APL) modem traffic instead of voice traffic.
In some parts of the country digital circuits are hard to obtain, and many
applications do not require the higher speeds of digital circuits. This application
allows customers to use existing modems while reducing the cost of using them
by eliminating access lines.
The T1 access unit supports up to three 8-port E&M APMs. A typical application
consists of:
Modem Lines – Eight lines
FEP-CC – 128 kbps
Router – 896 kbps
E&M is used to transport the analog information, and no E&M signaling is
involved. In fact, the E&M signaling leads are disconnected in this application (the
operating mode is set to Transmit Only). See Chapter 4,
information on configuring voice ports.

Channel Bank Replacement and Additions
In the example shown in the following diagram, the T1 access unit is a
replacement for a channel bank. The T1 access unit is more than just a
replacement for a channel bank. It can do many things that a channel bank
cannot do. A channel bank has no data ports, it passes data as if it comes from
external modems or DSUs. The T1 access unit provides both data and voice
ports. A channel bank is a “dumb” device, and therefore cannot be managed from
a remote site, while the T1 access unit can be managed via SNMP.

OCU-DP APM converts the 56K digital format from the line side into a digital DS0
format. This DS0 format contains the 56K of data plus the necessary signaling
information required to set up the call to the far-end video equipment.

Applications
Consolidated T1 Access of DDS Circuits
The following example illustrates how to use the OCU-DP APM to reduce facility
costs associated with point-to-point 56/64K connections by consolidating these
lines into a single T1 facility. The T1 Access Muxes shown in this application
could also be used to support both voice and high-speed data.
Typically, T1 Access Muxes are placed at concentration points where a single T1
line is less costly than multiple (typically four or five) 56K lines. If DSUs are left at
both ends of the circuit, proprietary DSU Network Management Systems can be
used. Or, circuits associated with remote DSUs can be terminated directly on a
Sync Data APM at the Data Center to eliminate Data Center DSUs.
The OCU-DP APM does not support subrate DDS rates. Subrate applications can
be supported by installing a Paradyne 3610 or similar device configured for
56/64K line speed.

Async Terminal User Interface Access
You can access the user interface:
Locally through a direct connection to the communications port via an async
terminal (or other VT100-compatible terminal) or PC emulation.
Remotely through a Telnet session, although only one user interface session
may be active at one time.
Network Management
Manage the T1 access unit via an SNMP management system connected to the
communications port or through a remote in-band connection.

Possible Settings: Internal, External
Default Setting: Internal
Determines whether the transmitted data is clocked by the synchronous data port
internal clock, or by the clock supplied by the DTE connected to the synchronous data
port.
Internal – The DCE clocks transmitted data, and uses the interchange circuit DB
(CCITT 1 14) – Transmit Signal Element Timing (TXC) (DCE source) for timing the
incoming transmitted data.
External – The DTE externally provides the clock for the transmitted data, and the
synchronous data port uses the interchange circuit DA (CCITT 113) – Transmit Signal
Element Timing (XTXC) (DTE source) for timing the incoming transmitted data.
NOTE: When external clock is used, it must be synchronized to the same clock
source as the system.
Invert Transmit Clock

controlled by the receipt of a DCLB-actuate and DCLB-release sequence (either V.54,
or FT1 [ANSI] compliant sequences) from the network or far end unit. When this
configuration is enabled (V.54, FT1, or Both), receiving a DCLB-actuate sequence on a
particular port causes the NAM to initiate a DCLB on that port (provided that a DCLB
can be performed based on the current state of the port and NAM). Receiving a
DCLB-release sequence terminates the DCLB.
Disable – Ignores the DCLB-actuate and DCLB-release for the port.
V.54 – DCLB-actuate and DCLB-release sequences that comply with the V.54 standard
for “inter-DCE signaling for point-to-point circuits” are recognized and will control the
initiation and termination of a DCLB (V.54 Loop 2) for the port.
FT1 – DCLB-actuate and DCLB-release sequences that comply with either the
ANSI.403, Annex B standard for “in-band signaling for fractional T1 (FT1) channel
loopbacks” are recognized and will control the initiation and termination of a DCLB for
the port.
Both – DCLB-actuate and DCLB-release sequences that comply with either the ANSI
or V.54 standard are recognized and will control the initiation and termination of a DCLB
for the port.

Pr ocedure
1. Follow this menu selection sequence:
Configuration Edit/Display→Cross Connect→DSX-1 to Network
Assignments
2. The DSX-1 to Network Assignments screen appears. This screen contains a
matrix of the current cross-connect status of all time slots on the Network
interface.
3. If you are using the 9261 Dual T1 NAM, you must choose which Network
interface to use. Enter 1 or 2 in the NETWORK field.
4. Move the cursor to the next editable timeslot (underlined). Use the spacebar
or type in the desired timeslot to display the desired timeslot assignment.
5. Repeat Step 3 until all desired timeslots are assigned. Select Save to save
the assignments, or press ESC to save and return to the Cross Connect
menu.
DSX-1 Signaling Assignments and Trunk Conditioning
The second page of the DSX-1 to Network 1/2 Assignments screen enables you
to define the signaling assignments and trunk conditioning for each timeslot on
the DSX-1 interface. You can specify whether robbed bit signaling information is
being passed within a given DS0, and the value of the signaling bits that will be
transmitted for that DS0 to the other cross-connected T1 interface if a Carrier
Group Alarm (CGA) occurs on a T1 interface.
Only those DSX-1-to-Network assignments from page 1 are displayed on this
page, from left to right and top to bottom in ascending order, by network and
timeslot.
When a CGA condition (LOS, OOF or AIS) is declared for a T1 interface, the
signaling bits being transmitted to the other T1 interface for the DS0 are forced to
idle for two seconds (except for user-defined patterns which are transmitted
immediately). This drops any call in progress. The signaling bits are then forced
to the selected state (Busy or Idle), and remain in this state until the CGA
condition clears. At this point, the received signaling bits from the T1 interface
which formerly had the CGA condition are passed through to the other T1
interface.
NOTE:
Trunk conditioning will only occur on DS0s that are cross-connected to
another T1 interface. All other DS0s remain unaffected by trunk conditioning.
Enter one of the values shown in Table 5-8 in each of the fields on both the
Network side and the DSX-1 side. Although you can choose any value for the
DSX-1 side, the default value displayed is based on a typical setting that would
be used with the corresponding Network side value. Typical pairs of values are
shown in the table below. If you change the setting of None to anything else, the
DSX side value is changed to the corresponding default value.
